Influence between UCLA and Standard Abutment on the Bone Loss around Implants

Abstract

This study is to clearly an influence of abutments on bone loss of implants. The bone loss of implants which were with use of UCLA and Standard abutment was investigated according to the range of age and the period after operation. They were under function for 3 to 6 years. The number of UCLA and Standard abutment was 60. The amount of bone loss was measured with pen-apical X-ray films which were taken with parallelig technique.
The following results were obtained ;
1, The bone loss of the mesial and distal side around fixtures was recognized in UCLA and Standard abutment.
2. The mesial and distal bone loss on UCLA and Standard abutment had no significance between the range of age and the period after operation. Comparing the mesial with the distal bone loss among abutments, the tendency that the amount of distal bone loss after 6 years was less than other years was shown, and also there was a significance (p<0.05) between UCLA and Standard abutment.
